SUBMAR INE S AVING DEVICE Filed OGtull, 1929 2 Sheet5-Sheet 2 Zmven or, Zdzzardq l fluirzra attorney Patented June 24, 1930 UNITED STATES EDUARDO F. QUINTEROS, OF BUENOS AIRES, ARGENTINA SUBMARINE SAVING DEVICE Application filed October 11, 1929, Serial No T he invention relates to a device for salvaging submarines and has essentiallyfor its object a simple mechanisi'n easy t appli* cation, beside facilitating the location of the exact position of the sunken submarine,

enables also the renewal of air, discharge of gases, provision of drinking water and even nourishment in extreme cases.

The invention also has equally in view other objects which will be explained as the description proceeds and which will be defined by the appended claims.

In order that this invention may be clearly understood and easily put into practice, an example is given in the accompany in g drawings, in which Figure 1 is a partial View of the submarine with the salvage arrangement applied.

Figures 2 and 3 are elevation and plan views respectively, of the buoy with its hose connection.

Figure & is a section of the collar of the buoy, taken on line 4-4 of Fig. 2.

Figure 5 is another section of the buoy, taken on the line 55 of Fig. 2.

Figures 6 and '7 are views of the top opening of the buoy showing the special closing arrangement.

Figure 8 is a perspective view in elevation of the grab-fastening of the buoy at the bridge of the submarine with arrangement for freeing both from the interior of the latter. The design shows in full lines the closed grab, and the dotted lines indicated it in the open position.

Figure 9 is a plan view of same.

In the drawings, the same reference numbers indicate corresponding parts throughout the several views.

In the form of construction represented, the salvage appliance is made up of a floating-buoy 1, preferably of a cylindrical form with conical ends which is attached to the hull of the submarine by a hose or hollow cable 2 the small end of which is connected with the conning tower of the submarine or other suitable part of same, communicating with its interior by means of a hatch (not shown) hermetically sealed.

. 398,956, and in Argentina August 23, 1929.

The hose 2 must be of? suilicient length to allow the buoy to reach the surface of the water when the depth at which it is sunk does not exceed that at which it may be possible to eilect the salvage; it should also be or" sullicient diameter so that its conduit divided in two by a longitudinal diaphragm l allows for the circulation and renewal of air by means of two ventilators (not shown) conveniently installed in the interior of the vessel, and able to assist the floating of the buoy.

The large end of the hose which runs through the whole length ofthe buoy is joined at the collar 5 of same, which collar terminates atits upper end with a lightroom or projecting chamber 6 wherein the luminous signals, flags or other similar distinctive objects are placed permitting of perfect visibility of same during both night and day.

In order to avoid liquid penetrating the interior of the hose, during the ascending movement 01" the buoy to the surface of the water, the nozzle of the top end is provided with a cover or valve closure 7 which is maintained against the aperture of the hose by hydraulic pressure, absolutely preventing the entrance of water. This cover is joined to an arm 8 provided with a counterweight 9 and both gyrate in turn around the hinge pin 10 mounted on chamber 6. It will be understood that whilst the nozzle of the tube is submerged, the hydraulic pressure, as previously stated, keeps it hermetically sealed against the cover 7 but once the nozzle appears on the surface the counterweight 9 will cause the rotation and opening of the cover, the counter-weighttaking a vertical position and the, cover in turn falling back on the counter-weight, both parts taking up the position indicated dotted lines in Figure 6, completely exposing to view the mouth of the tube and the signalbox room. 'lVith the pressure from the ai.r-. extracting an, (not shown) the opening of the cover 7 of the tube can also be eiilected and tested. 7

The buoy-l and hose 2 shall be placed in the position and form determined by the ice naval authorities; either around the tower or bridge of the submarine or in a box con structed aboard, arranged in both cases in such a way that the grabs shown in Figures 8 and 9 attached to both can be released from the interior of the submarine, modifying or adapting its form or reducing one. of its grabs, hook or frame in case it is found necessary to keep the cover of box or chest closed.

Figures 8 and 9 show the grab formed of two curved arms 11 preferably of laminated iron, which articulate independently, and with a pin 12 at the end of a worm-screw 13. On the plate 14 of the hull of the submarine is attached a double crutch 15 provided with two pins 16 which are movably engageable in the seats 17 of the swiveled arms 11. -Against the inner plate of the hull of the submarine is a handle 19 that screws. on the end of the worm-screw 13 which screws on to a fixed nut 20 joined by 21 to 22 forming a single piece.

It will be clearly seen from Figure 8, which shows in full lines the position for fastening the buoy, that in the event of the sinking of the submarine there is nothing else to do but turn the lever 19 which pushes the screw 13 outwards, causing the opening of the arm 11 to the position indicated by dotted lines; the buoy will then be freed and will rise to the surface permitting the location of the exact position of the submarineand, by means of the hose, the pumping of air whilst the workof rescue is being effected.

The operation in the form as expressed above is clearly appreciated and does not require any further explanation to those skilled in the art. 1

It is obvious that various structural modifications and details can be introduced without departing from the principle of the invention, which is clearly set out in the rights of claims following the descriptive memorandum.

. WVhat I claim is:

1. In a submarine salvaging device, a floating buoy adapted to be released from the submarine vessel when submerged; means for detachably securing said buoy to the vessel; means operable from within the vessel for releasing said buoy; a hollow cable divided by a longitudinal diaphragm throughoutits length and communicating with the interior of the vessel, said cable extending through the buoy longitudinally thereof and having fluid-tight connection with the buoy; and a chamber projecting beyond the top of the buoy and having its lower end in fluid-tight communication therewith and with the outlet end of said cable.

'2. In a submarine salvaging device, a

floating buoy adapted to be released from the submarine vessel when submerged; means for detachably securing said buoy to the vessel; means operable from within the vessel for releasing said buoy; a hollow cable having a diaphragm extending longitudinally thereof andforming separate conduits throughout its entire length; said cable extending through the float longitudinally thereof and having fluid-tight connection therewith at top and bottom thereof; a chamber projecting beyond the top of the float and having its lower end in fluid-tight communication therewith and with said cable; a valve closure for said chamber adapted to be sealed by water pressure when the buoy is submerged, and means for automatically opening said closure when the chamber is exposed above the surface of the water. a

In testimony whereof I affix my signature.
